株洲市城市植物景观分析

应用景观生态学原理,结合株洲市城市绿地植物景观现状,选取多样性指数、优势度、分离度和破碎度4个指标,从景观的类型多样性、格局多样性和斑块多样性3个方面,对株洲市城市植物景观进行多样性分析。结果表明,随着人类活动的加强,城市植物景观类型多样性降低,景观类型趋于单一;景观斑块多样性增大,嵌块体形状更趋复杂;景观格局复杂化,结构不稳定性提高,自我组织调节、修复能力削弱。最后,对株洲城市绿地景观的改善提出若干建议。

Analysis of urban plant-landscape in Zhuzhou City

Based on the principle of landscape ecology the current situation of urban vegetation-landscapes(UVL) in Zhuzhou was studied.The diversity of UVL of Zhuzhou City was analyzed in the paper which including the diversity,dominance,fragmentation and isolation,four indices and the vegetation-landscape type diversity(TD),pattern diversity(Pn D) and patch diversity(PD) three aspects.The result shows that with the strengthening of human activity,TD decreases and the landscape types tend to be more simple;PD increases and the shapes of patches become more complex;Pn D become more complex,and the stability of the vegetation-landscape structure decreases and the ability of self-regulation weakens.Finally,some suggestions were introduced to improve the quality of urban vegetation landscapes.
